Retainer for at least partially annular gas supply lines of a stationary gas turbine

Abstract

A stationary gas turbine having at least one at least partially annular gas supply line, which is supported by a retainer, wherein the gas turbine has in the interior thereof a main flow direction of the working fluids, and wherein the retainer has at least one floor retainer supported against the floor and a face retainer attached to the housing of the gas turbine on the side opposite the floor retainer, and wherein both the floor retainer and the face retainer support the gas supply line against motion both in the main flow direction and perpendicularly thereto, wherein the face retainer has a spring system, which in particular compensates the change in the extent of the housing during operation of the gas turbine.

The invention claimed is: 
     
       1. A stationary gas turbine having
 at least one at least partially annular gas supply line which is supported by a retainer, 
 wherein the gas turbine in an interior of the at least one at least partially annular gas supply line comprises a main flow direction of operating fluids, 
 wherein the retainer comprises at least one floor retainer which is supported in relation to a floor and is not attached to a housing of the gas turbine, and an end face retainer which is attached to the housing of the gas turbine on that side that is opposite the at least one floor retainer, and wherein both the at least one floor retainer as well as the end face retainer support the at least one at least partially annular gas supply line in relation to both movement in the main flow direction as well as perpendicular to the main flow direction, 
 wherein the end face retainer in regular operation of the gas turbine is provided on an apex of the housing and comprises a spring system which compensates for expansion of the housing during operation of the gas turbine, 
 wherein the retainer further comprises at least two lateral retainers which each support the at least one at least partially annular gas supply line on mutually opposite sides of the gas turbine, and 
 wherein the at least two lateral retainers provide support only in relation to movement in the main flow direction. 
 
     
     
       2. A stationary gas turbine, comprising:
 an at least partially annular gas supply line surrounding the gas turbine; 
 a floor retainer disposed on a floor and under the at least partially annular gas supply line, secured to the at least partially annular gas supply line, and configured to transmit a portion of a dead weight of the at least partially annular gas supply line directly to the floor; and 
 an end face retainer secured to a top of a housing of the gas turbine, secured to a top of the at least partially annular gas supply line, and configured to transmit a remainder of the dead weight of the at least partially annular gas supply line directly to the housing; 
 wherein the end face retainer comprises a spring system configured to compensate for expansion of the housing of the gas turbine during operation. 
 
     
     
       3. The stationary gas turbine of  claim 2 , wherein the floor retainer and the end face retainer also constrain the at least partially annular gas supply line from movement in a main flow direction of operating fluids in the gas turbine. 
     
     
       4. The stationary gas turbine of  claim 2 , further comprising at least two lateral retainers, each disposed on an opposite side of the at least partially annular gas supply line between the floor retainer and the end face retainer, and each configured to provide support only in relation to movement in the main flow direction. 
     
     
       5. The stationary gas turbine of  claim 2 , wherein the floor retainer is disposed under the gas turbine. 
     
     
       6. The stationary gas turbine of  claim 2 , wherein the floor retainer and the end face retainer are positioned at six o'clock and twelve o'clock respectively. 
     
     
       7. A stationary gas turbine, comprising:
 at least one at least partially annular gas supply line which is supported by a retainer, 
 wherein the gas turbine in an interior of the at least one at least partially annular gas supply line defines a main flow direction of operating fluids, 
 wherein the retainer comprises: at least one floor retainer which is supported by a floor, disposed under a bottom of the at least one at least partially annular gas supply line, attached to the at least one at least partially annular gas supply line, and which is not attached to a housing of the gas turbine; and an end face retainer which is attached to the housing of the gas turbine on a side that is opposite the at least one floor retainer, and wherein both the at least one floor retainer as well as the end face retainer support the at least one at least partially annular gas supply line in relation to both movement in the main flow direction as well as perpendicular to the main flow direction, and 
 wherein the end face retainer in regular operation of the gas turbine is provided on an apex of the housing and comprises a spring system which compensates for a variation an expansion of the housing during operation of the gas turbine. 
 
     
     
       8. The gas turbine as claimed in  claim 7 ,
 wherein the end face retainer comprises a first connection region which is fixedly connected to the housing of the gas turbine, as well as a second connection region which is supported by the housing of the gas turbine but is not fixedly connected to the housing. 
 
     
     
       9. The gas turbine as claimed in  claim 7 ,
 wherein the at least one at least partially annular gas supply line and the retainer are provided in a region of the housing of the gas turbine that comprises no guide vane adjustment installation. 
 
     
     
       10. The gas turbine as claimed in  7 , wherein only the at least one floor retainer and the end face retainer support a dead weight of the at least one at least partially annular gas supply line. 
     
     
       11. The gas turbine as claimed in  claim 7 ,
 wherein the at least one floor retainer is not connected to the housing of the gas turbine. 
 
     
     
       12. The gas turbine as claimed in  claim 11 ,

       13. The gas turbine as claimed in  claim 7 ,
 wherein the retainer furthermore comprises at least two lateral retainers which each support the at least one at least partially annular gas supply line on mutually opposite sides of the gas turbine. 
 
     
     
       14. The gas turbine as claimed in  claim 13 ,
 wherein the at least two lateral retainers are not connected to the housing of the gas turbine. 
 
     
     
       15. The gas turbine as claimed in  claim 14 ,
 wherein the at least two lateral retainers are supported in relation to the floor and are anchored in a foundation of the gas turbine. 
 
     
     
       16. The gas turbine as claimed in  claim 13 ,
 wherein the at least two lateral retainers do not completely encompass the at least one at least partially annular gas supply line. 
 
     
     
       17. The gas turbine as claimed in  claim 16 ,
 wherein the at least two lateral retainers support the at least one at least partially annular gas supply line in only two mutually opposite regions which are not interconnected.
